Merge tag 's390-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull more s390 updates from Heiko Carstens:
 "Just a couple of small improvements, bug fixes and cleanups:

   - Add Eric Farman as maintainer for s390 virtio drivers.

   - Improve machine check handling, and avoid incorrectly injecting a
     machine check into a kvm guest.

   - Add cond_resched() call to gmap page table walker in order to avoid
     possible huge latencies. Also use non-quiesing sske instruction to
     speed up storage key handling.

   - Add __GFP_NORETRY to KEXEC_CONTROL_MEMORY_GFP so s390 behaves
     similar like common code.

   - Get sie control block address from correct stack slot in perf event
     code. This fixes potential random memory accesses.

   - Change uaccess code so that the exception handler sets the result
     of get_user() and __get_kernel_nofault() to zero in case of a
     fault. Until now this was done via input parameters for inline
     assemblies. Doing it via fault handling is what most or even all
     other architectures are doing.

   - Couple of other small cleanups and fixes"
